K00-K14: Diseases of oral cavity, salivary glands and jaws

The diseases of the oral cavity, salivary glands, and jaws (ICD codes K00-K14) encompass a wide range of disorders that can impact the mouth and nearby structures. These conditions can originate from various causes, such as bacterial or viral infections, genetic factors, unhealthy lifestyle choices, or physical injuries. General symptoms might include pain, swelling, altered taste, bad breath, or difficulties in eating, speaking, or swallowing. Conditions affecting teeth and gums, such as tooth decay or gingivitis, form part of this group. Various types of cysts, tumors, and changes in the size and flow of saliva are also included. Conditions like oral cancer are relatively rare but potentially serious. In many cases, these diseases progress gradually, possibly leading to complications if left unaddressed; however, most conditions are treatable, particularly if diagnosed early.
